概周期系数的时滞微分方程概周期解的存在性

Almost periodic solution to delayed cubic differential equations with almost periodic coefficients

在Banach空间中,运用二分性、不动点定理、等度连续和Ascoli定理等理论,研究一类五次概周期系数的时滞微分方程组概周期解的存在性,得到此类微分方程组的概周期解存在的充分性定理。

In banach spaces, by means of exponential dichotomy, fixed point theorem, equicontinuity ＆ As-coli theorem,the existence of almost periodic solution of delayed quintic differential equations with almost periodic coefficients is investigated, so this sufficient theorem is obtained.
